Abstract

An automobile seat includes a seat cushion frame, a side frame mounted on the seat cushion frame, and a seat back frame mounted on the side frame so as to be rotatable within a limited angle. An elastic member is mounted on one of the side frame and the seat back frame, while a guide portion having a holding portion for holding the elastic member is formed on the other of the side frame and the seat back frame, the guide portion. The seat back frame is fixed to the side frame in a normal sitting condition in which the elastic member is held in the holding portion. In the case where a load greater than a predetermined value is inputted from behind, a lower portion of the seat back frame is pushed by a lumbar part of a seat occupant upon a rearward movement of the seat occupant to thereby deform the elastic member, which in turn leaves the holding portion and moves rearwards along the guide portion, thus causing the seat back frame to rotate with respect to the side frame and causing the headrest to move forwards.
